A Group of Materials Called Perovskites Could Be a Game

Oct 19, 20200183;32;The thing about perovskites compared to silicon is that they have extremely high absorption constant. Thus, the active layer of a perovskite cell can be less than a micron thick. The amount of lead in that is going to be trivial. She's right, though, the extreme sensitivity to humidity so far has been the real issue.
